[Solved] Question about Spot Light (Flash Light simul)

[tranlong021988]

I'm simulating a flash light effect, PG here: http://www.babylonjs-playground.com/#1OTIFL#1

As you can see, the floor using same material with the wall, but always look darker, especially at the edge, I think it is not like realistic. Is it working fine or I miss something ?

Hello, this is because the light is almost parallel to the ground

You can try to lower the direction of the light on y axis:

@Deltakosh even if lowering direction, it still darker than usual, you can check new PG here, drag around to see unrealistic behavior: http://www.babylonjs-playground.com/#1OTIFL#3

And this is a simulation, parallel direction(render with 3ds max with simple diffuse texture):

Woot well done! it was a bug in my shader

I fixed it, your PG should work now (clear your cache first)

DK - Thank God you came along, as I spent over an hour yesterday trying to solve this for @tranlong021988. I came back today becuse I reconstructed the scene several times and got the same response. I simply didn't want to look like the village idiot, as there aren't often bugs that pop up of this nature with known lights on standard materials. Next time, I'll post any results I find sooner.
